species has such a wide distribution as the Chimpanzee. It is found in West and Central Equatorial Africa, from Gambia in the north to Angola in the south. Several specimens have been obtained from the neighbourhood of Lake Tanganyika, the Xiam-Niam country and Uganda. The LTganda Chimpanzee has been given the specific name Anthropopitheeus $chit:einfurthi.
Classification.—As the external characters of the Chimpanzee exhibit considerable variation with age, sex and locality, it is not surprising to discover, on consulting the literature dealing with taxonomy, that zoologists have invented specific names for mere varieties. And Trouessart has collected the various svnonvms which

have been applied to the two real species—the Common Chimpanzee (Antliropopitliecus troglodytes} and the Bald-headed Chimpanzee (A. calms).
(a)  The    Common    Chimpanzee    (A.    troglodytes Linn).
Synonyms.—A. sylcestris (Tyson and Cowper); A. niger (E. Geoff) ; J. Icucoprymnus iLess) ; A. cellerosus (Gray); A. schiceinfurthi (Gigl) : A. aitbryi (Gratiolet et Alix;.
(b)  The Bald-headed Chimpanzee  (A. calms, Du Chaillu).
Synonyms.—A. tschego (Duvernoy) ; A. kooloo-kamba CDu Chaillu).
Some of these authors employed the old generic name Troglodytes instead of the modern Anthropopitheeus.
Many fine illustrations of A. troglodytes have been published, and Bartlett (303) gives a fine plate representing A. calvus. He contrasts the external characters and habits of the two species. The face, hands and
